This study was aimed at evaluating the electrophoresis profile of serum protein in broilers fed with diets containing aflatoxins and natural clinoptilolite clay. Five hundred and twenty eight male broilers Ross were distributed in six treatments and each one with 4 replications: T1 - control (without aflatoxins or clinoptilolite), T2 -5ppm of aflatoxins, T3 -0.25% of clinoptilolite, T4 -5ppm of aflatoxins and 0.25% of clinoptilolite, T5 -0.5% of clinoptilolite and T6 - 5ppm of aflatoxins and 0.5% of clinoptilolite. The broilers were allocated in 24 boxes and submitted to a treatments for 42 days, when they were slaughtered. Total proteins, albumin fractions, alpha 1, alpha 2, beta and gamma were analyzed. Except gamma fraction the Tukey test showed differences (P<0.05) on serum total proteins and proteins fractions in all treatments which aflatoxin was present. The clinoptilolite did not modify (P<0.05) the serum proteins. The control broilers fed with diets containing aflatoxins and clinoptilolite presented low levels (P<0.05) of total protein, albumin, and globulins (alpha and beta fractions). In conclusion, aflatoxins change the electrophoresis profile and clinoptilolite is not able to protect avoid these changes.
